DETAILED DESCRIPTION

FIG. 1 illustrates a front view of an example fiber management tray 10 (e.g., patch tray). In this example, one tray is depicted. It will be appreciated that multiple trays may be used and stacked in groups or blocks which form a stacked arrangement as shown in FIG. 3. The tray 10 includes a body 12, a flat bottom wall 14, and opposing side walls 16 extending outwardly therefrom. The tray 10 includes a tray axis 5 and a termination region 18 that extends along the tray axis 5. The termination region 18 can define one or more of fiber terminations, fiber splitters, fiber splices, or other fiber components. Various structures can be provided in the termination region 18 including splices and/or storage of cables. Various additional structures can be provided for managing and organizing the fiber optic cables, including a divider wall and cable retention tabs.

The termination region 18 includes a termination panel 13 that holds connectors 20 which are used to align connectors for transmission of fiber optic signals. In one example, the termination panel 13 can hold connectors 20 which allow for interconnection of two connectorized ends of cables. The termination panel 13 can include one or more integrally formed adapter blocks 22. In the depicted example, the adapter blocks 22 include four adapters that are each duplex adapters. In other examples, the adapter blocks 22 can include single adapters. The adapter blocks 22 interconnect two fiber optic connectors.

The termination panel 13 can be configured to extend along the tray axis 5 such that it divides the termination region 18 into a first side 24 and a second side 26. The first side 24 of the termination region 18 can be adapted to receive incoming distribution cable while the second side 26 of the termination region 18 can be adapted for outgoing cable. In one example, connectorized ends of the pigtails can be optically connected to adapters provided on the termination panel 13. The incoming optical fibers can be configured to bring in signals while the outgoing optical fiber leaves the tray 10 to be one-to-one connected or spliced. In some examples, the outgoing optical fiber can be passed through a splitter or other optical device. For example, incoming distribution fiber pigtails 7 can be routed to the first side 24 and outgoing distribution fiber pigtails 9 can be routed from the second side 26 as shown in FIG. 5. The pigtails from the first and second sides 24, 26 can be separated on the tray 10 to prevent crossover. Details of the separate routing paths for the incoming and outgoing distribution fiber pigtails 7, 9 are described in further detail below.

The tray 10 can include cable management elements 28 for holding incoming cables or fiber tubes inside the tray 10. Elements 28 can include hooks, tabs, ties, and other devices for guiding and managing cables or tubes. In one example, the elements 28 can be positioned along the side walls 16 of the tray 10 and generally extend over the bottom wall 14 to manage optical fiber.

Referring to FIG. 2, the back side of the tray 10 is depicted. In some examples, the bottom wall 14 of the tray 10 can define a plurality of openings 30. The openings 30 are configured such that multiple adapters can be accessible therethrough. The openings 30 can allow an operator to grasp the connector 20 through the openings 30 without interference with adjacent connectors 20. For example, the openings 30 can permit finger access for handling pigtails for re-patching or adding pigtails. Thus, it is not necessary to have finger access between the adjacent adapters as the operator can handle the connectors on the tray 10 through the openings 30 that allow for quick access for connecting or disconnecting the connectors on the termination panel 13. In one example, the bottom wall 14 of the tray 10 can include four openings 30 on each of the first and second sides 24, 26 of the termination region 18.

In other examples, the tray 10 can include a middle portion 32 (e.g., storage basket). The middle portion 32 can have a first pocket 44 (see FIG. 1) and an opposite second pocket 48 (see FIG. 2). Each of the first and second pockets 44, 48 can respectively include a base 38 a, 38 b, side portions 40 surrounding the base 38 a, 38 b, and cable fixation clamps 46 extending generally from the side portions 40. In one example, the side portions 40 can cooperate with the base 38 a to form the first pocket 44 (e.g., storage area) for storing slack or loops of cable. The side portions 40 can cooperate with the base 38 b to form the second pocket 48 (e.g., storage area) for storing slack or loops of cable.

In one example, the first pocket 44 of the middle portion 32 can communicate with the second side 26 of the termination region 18 of the tray 10. The first pocket 44 can include a dedicated entrance 49 for the outgoing distribution fiber pigtails 9. The outgoing distribution fiber pigtails 9 can be routed from the second side 26 of the termination panel 13 to the first pocket 44 as shown in FIG. 5 and be lead along a first pathway 15. Coils of the slack lengths of the outgoing distribution fiber pigtails 9 can be retained by the cable fixation clamps 46 and guide rings or guide walls 11 (see FIG. 1) within the first pocket 44. In other words, after positioning of the stored cable in the first pocket 44 of the middle portion 32, the cable fixation clamps 46 can hold the stored cable down properly relative to the base 38 a. In some examples, the outgoing distribution fiber pigtails 9 positioned at the second side 26 of the termination panel 13 can be outgoing cables directly to the customer. The dedicated entrance 49 and first pathway 15 can help to eliminate crossings of the outgoing distribution fiber pigtails 9 with the incoming distribution fiber pigtails 7 at the first side 24 of the termination panel 13.

The second pocket 48 can be configured as over storage for storing loops of the incoming distribution fiber pigtails 7. After positioning of the stored cable within the second pocket 48, the cable fixation clamps 46 can hold the stored cable down properly relative to the base 38 b. The first side 24 of the termination panel 13 can include the incoming distribution fiber pigtails 7 routed from a splitter. In some examples, the incoming distribution fiber pigtails 7 can be configured and routed on the tray 10 while in a factory such that there is no need to manipulate the incoming distribution fiber pigtails 7 from a backside 25 of the tray 10. The second pocket 48 can include an entrance 50 opposite the dedicated entrance 49 for leading the incoming distribution fiber pigtails 7 along second pathway 17 to the second pocket 48 for storing slack or loops of cable. It will be appreciated that the tray 10 may be molded in a mirror image to allow incoming and outgoing cables to be switched to opposite pathways on the tray 10.

The second pocket 48 of the middle portion 32 can communicate with the first side 24 of the termination region 18 of the tray 10. In one example, the second pocket 48 can include a turn over point 54 (e.g., fiber transition opening) to permit cable to be routed therethrough to an opposite side of the tray 10. The turn over point 54 can have an access structure for allowing optical fibers to be inserted into the turn over point 54.

In one example, the incoming distribution fiber pigtails 7 can be routed in the entrance 50 to the second pocket 48 where the incoming distribution fiber pigtails 7 can be looped. In other words, a substantial length of slack cable can be routed to the second pocket 48. In other examples, incoming distribution fiber pigtails 7 can be routed through the turn over point 54 to the first side 24 of the termination panel 13 as shown in FIG. 5.

Referring to FIG. 3, a first cover 60 may be used to cover the middle portion 32 of the tray 10. For example, a first cover 60 may be used to cover the first pocket 44 and a second cover 61 may be used to cover the second pocket 48. The covers 60, 61 can help to retain the pigtails looped therein. In one example, the covers 60, 61 can be used to form a partially enclosed basket area for storage of pigtails. The covers 60, 61 can be secured in the closed position by clamps, latches, straps or any other suitable mechanism, such as, capture arms 42. The covers 60, 61 may be made of a lightweight, structurally flexible material, such as a polymeric material or molded plastic. In some examples, the tray 10 may be made of similar materials as covers 60, 61. An example cover is illustrated and described in more detail with reference to FIG. 8.

In other examples, the tray 10 can include a hinge 56 (see FIGS. 1 and 2) for mounting to a tray tower 58 (e.g., mounting bracket). A part of the hinge 56 is shown in FIG. 1 and the other part in FIG. 3. The hinge 56 has a hinge axis 55 that is perpendicular to the tray axis 5. The tray 10 is adapted to pivot around the hinge axis 55. In one example, the hinge 56 can include pins 57 on the tray 10 and clips 19 (see FIG. 3) on the tray tower 58 for holding the pins 57. In other examples, the pins 57 and clips 19 may be reversed such that the pins 57 are configured on the tray tower 58 and the clips 19 are configured on the tray 10.

The Multiple trays 10 are shown in FIG. 3 attached to the tray tower 58. To attach the trays 10 to the tray tower 58 the pins 57 of the hinge 56 can be snapped into the clips 19 on the tray tower 58. The stacked trays 10 may be assembled in known or other suitable manner. For example, the trays 10 can be pivotally mounted on the tray tower 58 to cantilever therefrom and pivot about the hinge axis 55. In one example, the trays 10 may be staggered vertically as mounted on the tray tower 58. In other examples, the trays 10 may be stacked horizontally.

Referring again to FIG. 3, the tray tower 58 can have a base 63 that defines a passageway 59 along each side of the tray tower 58 for routing cable into and out of the tray tower 58. In certain examples, the passageway 59 may be used for running cable along the sides of the tray tower 58 horizontally to the tray 10. The cable can be routed up the tray tower 58 as shown in FIG. 5 and curved into either the first or second pocket 44, 48 for storing slack or loops of cable and routed to the respective first or second side 24, 26 of the termination region 18. In some examples, cable may be routed into and out of a splice.

Referring to FIG. 4, lower ones of the trays in the stack can be accessed without removal of superposed trays. One end of the stack can be lifted upwardly or pivoted. After work within that tray is completed, it can be returned to its located position in the stack merely by reversing the procedure. In some examples, the middle portion 32 can be located between the hinge 56 of the tray 10 and the termination region 18. In one example, multiple trays may be stacked in groups or blocks that form a stacked arrangement.

A portion of first and second pathways 15, 17 are positioned adjacent to the hinge 56 to avoid potentially damaging cable pull during pivoting movement of trays. Flanges 21 can help maintain cables in the first and second pathways 15, 17. The middle portion 32 includes the first and second pathways 15, 17 that extend to either side of tray 10 to supply cables to the termination panel 13 and each of the first and second pockets 44, 48. Having separate first and second pathways 15, 17 generally allow cables to pass close to the hinge 56 without crossing over to help keep incoming and outgoing cables separate.

Referring to FIG. 6, an example splice tray 62 is shown. Splice holder mounting locations 64 (e.g., receptacles) are provided for receiving and retaining splice holders used to hold splice sleeves that protect fusion splices between cables and fibers of a through cable. The non-connectorized ends of the pigtails/stub assembly can be spliced to fibers from a main cable at the splice tray. In certain examples, fiber management trays in accordance with the principles of the present disclosure can include structures for mounting optical fiber splices and/or passive optical components on major sides of the trays. In other examples, outputs of optical components can be routed to a topmost side 66 of the splice tray 62 for splicing to cables. Outputs of the optical component can also be spliced to optical fibers for forward feeding and/or back feeding signals through the main fiber optic cable. The splice tray 62 can include fiber routing paths for routing excess fiber in looped configurations that prevent the fibers from being bent beyond their minimum bend radius requirements. Additionally, the splice tray 62 can retain and protect fiber optic components such as passive optical splitters and/or wavelength division multiplexors.

FIGS. 7-8 show views of an embodiment of another fiber management tray 100. FIGS. 7-8 show the tray 100 having substantially the same features as the embodiment shown in FIGS. 1-6.

The tray 100 includes a cover 160 having a plurality of snap-fit interlocks 102 around a perimeter of the cover 160. The snap-fit interlocks 102 can be used to secure the cover 160 to the tray 100. The cover 160 also defines an aperture 112 configured to receive a portion of a finger 120 formed on the tray 100 to help retain and control cables. The cover 160 further includes a recess 116 for receiving the cable fixation clamp 46 on the tray 100. The snap-fit interlocks 102 are illustrated and described in more detail with reference to FIG. 9.

Referring to FIG. 9, an enlarged view of the cover 160 is shown detached from the tray 100. In this example, the snap-fit interlocks 102 on the cover 160 includes slots 104 with a flexible cantilever 106 positioned therebetween. The slots 104 can be configured to receive capture arms 142 on the tray 100. The capture arms 142 can define a receptacle 108. The cover 160 can be snapped into the tray 100 by the snap-fit interlock 102. To initiate the interlock process, the flexible cantilever 106 can be configured to be manually pressed to cause the flexible cantilever 106 to be manually snapped into the receptacle 108. The capture arms 142 can each include a retention feature 110 that extends outwardly into the receptacle 108 to help retain the flexible cantilever 106 therein. The cover 160 can be easily lifted out of the tray 100 by disengaging the flexible cantilever 106 from the receptacle 108.

Referring to FIG. 10, only portions of the tray 100 is shown for purposes of describing details of a first pocket 144. The first pocket 144 has substantially the same features as the first pocket 44 shown in FIG. 1.

The tray 100 provides better organization for multiple loops of each fiber. If multiple loops are required, the tray 100 provides improved management of those cables. The first pocket 144 includes a rib 122 on a bottom wall 114 of the tray 100. The rib 122 helps to organize and retain looped cables within the first pocket 144. In certain examples, the finger 120 can extend upwardly into the first pocket 144 to help control or manage the cable slack or loops in the first pocket 144. The finger 120 has a first height H₁ such that it may accommodate as much cable as possible underneath without having to raise a second height H₂ of the tray 100. The finger 120 is tall enough such that it can be received within the aperture 112 of the cover 160. It will be appreciated that the heights H₁, H₂ of the finger 120 and the tray 100 may vary with other embodiments. The finger 120 configuration can create a narrow channel 124 on the tray 100 for feeding cables into the first pocket 144. The narrow channel 124 is separate from the first pocket 144 and helps to manage the cable routed to the second side 26 of the termination region 18.

Referring to FIG. 11, an enlarged view of a portion of FIG. 10 is shown to illustrate a dedicated entrance 149 for routing cable into the first pocket 144 of the tray 100. As described above, the cable can be routed into the first pocket 144 through the dedicated entrance 149 where a plurality of cable fixation clamps 46 can be used to help retain the cable. A desired length of cable can be looped within the first pocket 144 and organized by the ribs 122 and cable fixation clamps 46. The finger 120 can help organize the cables while it provides for the narrow channel 124 whereby the cables can be better aligned for entering a termination region 118.

Referring to FIG. 12, an enlarged view of a backside 125 of the tray 100 is shown. The tray 100 includes a second pocket 148 that has substantially the same features as the second pocket 48 shown in FIG. 2.

Similarly to the first pocket 144, the second pocket 148 also includes the finger 120 described above. The second pocket 148 has an entrance 150 for cables that is separate from the dedicated entrance 149 of the first pocket 144. FIG. 13 shows an enlarged view of the entrance 150. Similarly to FIG. 5, the slack or loops of cables are routed through the entrance 150 and stored within the second pocket 148. The tray 100 also includes a turn over point 154 for routing cable at the backside 125 of the tray 100 from the second pocket 148 through the narrow channel 124 to the first side 24 of the termination region 118. The routing of the cable is similar to that described above in reference to FIG. 2. It will be appreciated that the tray 100 may be molded in a mirror image to allow incoming and outgoing cables to be switched to opposite pathways on the tray 10.

Referring to FIG. 14, the backside 125 of the tray 100 is depicted. A portion of the termination region 118 is shown detailing the connectors 20. A plurality of openings 130 are defined within the bottom 114 of the tray 100 as described above with reference to FIG. 2. As shown, each of the openings 130 includes two connectors 20. The openings 130 defined in the bottom wall 114 allow an operator to easily take hold of the connectors 20 using just two fingers, for example, from top to bottom. Thus, it is not necessary to take hold of the connectors 20 at adjacent sides. The openings 130 are configured such that an operator can grasp the connectors 20 through the openings 130 without interference with adjacent connectors 20.

FIGS. 15-16 show a stacked configuration of a plurality of the trays on a tray tower 158 in which the trays can pivot thereon as described above. Although three trays are shown, it will be appreciated that any number of trays may be mounted on the tray tower 158. Features of the pivoting trays 100 and the tray tower 158 are similar to FIGS. 3-6 described above.

From the forgoing detailed description, it will be evident that modifications and variations can be made without departing from the spirit and scope of the disclosure.
